Some more backstory on the Pi Swarm I was really excited when Amazon announced their Lambda offering. I thought that it was an awesome idea, but for the lack of an open solution and that it locked you into javascript. I believe that using Docker, we can have a relatively simple Amazon Lambda work-alike which …

Note: This behaviour was observed on a Pi B+; it was not observed on a Pi 2. I happened to have top up while doing the bonded Nic test and noticed that the load was awfully high. Then the following popped up: Cron pretty much has the CPU pegged. Once I saw this, I wondered …

Apologies to W. Somerset Maugham for the title. For my Cloud in a Box, I want the Data hosts, at the least to have “more” network I/O capability, whether it be for a Docker Registry or other data. (As an aside, I am playing with doing substructure matching of chemical compounds and/or other Cheminformatics with …

There is nothing wrong with your docker host. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the …

As a part of building out the Cloud in a Box, I wanted some storage for Docker images, as well as data. Based upon my previous experience, I believed that a SSD would be faster than a Micro SD, but I hadn’t tested it as yet. The challenge from Dieter Reuter (@Quintus23M), asking how I’d …

Docker Swarm supports a variety of methods for discovering swarm members. Each has arguments in its favor. In this post I shall discuss the various methods and thoughts regarding each. Background I originally started with the idea of having a portable cluster, a “cloud in a box” if you will, so that I could go …

This episode will consist of a quick aside to build a Docker Registry Mirror. Previous: Part 1 Why Do We Need a Mirror?? The Docker Registry is, to my mind, one of the greatest contributors to the rapid growth of Docker. Having a central location for images encourages sharing and re-use. Obviously some images are …

I’ve made a port of gliderlabs/registrator to the raspberry pi. The repository for the Pi port is at: nimblestratus/registrator. At first glance, the part I find most interesting is the size of the resulting image — ~12M. I firmly believe it’s a direct result of starting from Alpine Linux. This will definitely warrant further investigation. …

This version is forked from http://github.com/progrium/docker-consul and runs on the Raspberry Pi. Thanks to Jeff Lindsay for all his hard work. I am merely standing on the shoulders of giants. This initial version is a bit largish — ~500Mb; I think it’s mostly due to needing a go build environment. I think I can use …
